Chephalon warns Fentora prescribers about possible adverse effects

FRAZER, Pa. Cephalon has sent letters to healthcare providers warning them to proper actions when selecting patients, dosages, and administration of their narcotic painkiller Fentora.

This comes as a result of deaths and other serious adverse events of people taking the medication. Cephalon has said that the patients were not appropriate candidates for the drug.

According to the FDA’s MedWatch site, “These deaths occurred as a result of improper patient selection (e.g., use in opioid nontolerant patients), improper dosing and/or improper product substitution. The healthcare professional letters provide key points regarding appropriate patient selection, and proper dosing and administration of Fentora (fentanyl buccal tablet) to reduce the risk of respiratory depression.”
